Hi FantomXR, do you still sell them? Thanks, Tilmann

Hi, I am looking for a few of these Modules. Even if you have made a controller with it, I am interested. If you have some for sale, please contact me. Thanks!

Hi Novski, sorry for my late reply, didnt get a notification ! i am located in Hamburg, Germany. do you habe some PICs or complete modules? i am interested in 4 modules/Pics thanks!

Hi, is there any chance to buy the preprogrammed PIC for this project anymore? Most of the old links are dead. I saw the blank PCB in a shop, but not a kit or the PIC... I would also buy a used kit or populated PCB. Thank You! Best, koerschgen

Hi everybody, I would like to know if it is possible to put a circuit like this between the bhp_mf_module and the Motorfader? My motors create a very loud Pam-noise, doesn't matter wich setting I use... I think this will go away with a DC-Voltage-control...?! (Like SSL Motorfader) Thanks!

Hi Zam, that is great news and great work! Would be very nice to see some pics :-) Yes, its a Neumann with Danner Kassettes. There is a few places where I can put some extra PCBs in, depends on the max cable length. Sounds like you also implemented some auto-buttons and status-leds... Is it still connected via HUI? Is there any plan to sell those pcbs? Best, K

Hi ZAM! How far are you with your variable Voltage driver? I am very interested in that solution, because I have the same problems regarding noise. Have an old neumann mixing desk that needs quiet, flying faders :-) What about the MC33030 ? Could that be an replacement for the L293D ? Thanks, Koerschgen

Nice! What kind of desk is that? Cheers, K.

Really nice picture, GiPitt! Are the red Faders only control Fader for you Daw, or do they hava a Audio Taper? What kind of Mixing Desk is this? Cheers, K.

btw, I will run the Fader Modules with Mackie Hui. Will it cause problems with HUI if I deactivate 4 of the Faders, because I only need 20 in my Setup? Answered the above question by myself... it works. small update: Today The Fader-board arrived, everything works fine from the first startup! Tested it with the old original Fader, works in general, but it took me the whole day to figure out a good setting. 12v was way to strong, even though the motor is rated that high. I ended up using 6v... (as you said, Thorsten) Its not that fast anymore, but it turned out that noise is a big problem... the best setting so far is MinDuty 15, MaxDuty 100 PWM Steps are at 30. Btw, couldt figure out how to load a saved "preset"... All of the saved Sys.ex Files were grayed out!? Am I missing something? Now I need to build the first Prototyp fader were the slider sits much tighter on the rail and can be adjusted, this will eleminate a bit more of the noise (wich comes 50/50 from the motor and from the Slider). Any Ideas how to lower the Noise a little bit more...? What can I change with "MF Deadband"? I experienced no differene when I changed it to other values... Thorsten, are you interested in testing a Fader? Maybe You find out something else to control these beasts... Thanks!

1000% And no free play, no rattlesnake inside, no noise (ok, a little bit...) The side panels are damped with felt.

Prototype of the new Motorfader

Oh, good, that saves me a lot of Money, because I will need about 15A for three Boards (for the unexpected worst case that all Faders are forced to stop...) The Motor I use is rated with 12v, but it seems to be that the engineers who designed the Fader back in the days gave them 15V... (see attachment) I think this PTC will bring a nice protection in combination with a sloblo Fuse for each Board: http://www.conrad.de/ce/de/product/551228/Bourns-Multifuse-Serie-MF-R-Abmessungen-74-mm-Abmessungen-74-mm-IH-03-A/SHOP_AREA_17392&promotionareaSearchDetail=005 Is there any need for Motor Suppression Capacitors? Thanks K

The reason why I have to use this Motor is, because I have an old desk which has big faders (130mm), so I need to build my own custom Faders. and I had the chance to get 30 old motorised faders with the mentioned coreless Motor (but without a Audio Taper). Its the oldschool Version with a big wheel mounted on a 10k Pot and driven with a nylon string. So I need to use this Motor (to keep the costs Low). If the Speed of the fader movement is to high, I could change the ratio of the "gear". (the Motor rotates 4 1/2 Turns if the fader is moved from bottom to top). In the Old Fader the Motor driver was the L293D to, so this Problem is solved. I saw in the original schematics that the Motor Supply was 15v, maybe to lower the current a Little Bit. Is it a Problem to use a switching Psu for the Motor Supply? Will this may cause Problems with the PWM Control? @TK: 15V isn´t that high I think... Do you mean high current instead? Thanks so far...!
